I suspect it won’t make much of a difference - Bio has one of the lower 4/5 score percentages and APs have little weight in admissions decisions anyway.
MIT as your example - they don’t even mention AP on their standardized testing page or their admissions statistics page. If they suggest sending all standardized test scores, which I can’t find, I suspect they are referring to all SAT and ACT test dates.
(Side note - do you have an additional unmentioned AP score? The six 5s plus a 3 and a 4 in your initial post wouldn’t meet the “4 or higher on eight or more of these exams.” criteria. Not that the specific title will mean much, if anything, on an application.)
